DSD-INT 2019 Modelling in DANUBIUS-RI-Bellafiore

  1. 1. Debora Bellafiore CNR-ISMAR
  2. 2. Why modelling River-Sea Systems (RSS) RSS are hot spots from several perspectives: • The majority of population lives close to water courses → health and security issues • Several human activities: • agriculture (use of water), • dams (energy), sediment supply (deposition/erosion issues, along the river and on the coast) • Exposed to extreme events: • flooding • storm surges • drought
  3. 3. • Effects of Climate Change are enlarged in these environments → water supply, SLR • Modelling can be the tool to tackle these issues and provide support for management Why modelling River-Sea Systems (RSS)
  4. 4. data information knowledge impact Supersites (living labs) All over Europe Hub Data Centre Technology Transfer Office data The DANUBIUS-RI components
  5. 5. General interactions between Nodes -Process understanding -Forecasting, gap filling -Cal-Val procedures -Model driven methodologies -Input data for DSS -DSS modelling tools -Socio-economic modelling -Dealing with uncertainties Observation data

  8. 8. Modelling Node Objectives ⚫ Model as an accurate representation of the physical, chemical and ecological situation in the supersites ⚫ Model as a laboratory for researchers ⚫ Model as the basis for socio-economic evaluations with stakeholders ⚫ Model as the basis for regional and local studies
  9. 9. The Modelling node Tools and services for researchers and stakeholders SERVICES Code optimization COMPUTING Modelling Scientific Agenda SOFTWARE COORDINATION
  10. 10. Interaction of Modeling Node with Supersites Models In situ EO Lab analyses Supersite 1 In situ Lab analyses Supersite 2 In situ Supersite 3 • Expert team to advice on modeling tools for the specific problem (following standards) through RI • Training • where models are absent, possible modeling implementation directly from the node (RI/Modelling Node team) Models • Advice on standards, protocols, data formats etc on following DANUBIUS commons Lab analyses RI Models
  11. 11. Scientific Vision Pool of experts for software development Pool of experts for service development
  12. 12. Scientific Vision – Integrated modelling (physical, chemical, ecological processes) Fluid mud Bacteria on particulate matter, exchange through water-sediment interface Extinction of light Biofilm Bed roughness Resuspension, wave damping Radiation stress HydrodynamicsWaves EcologySediments Wave damping Chemistry Biology
  13. 13. Towards a Science Plan for DANUBIUS-RI “Making River-Sea Systems Work” Overarching issue Climate Change and Extreme Events Three major issues related to River- Sea-System: • Water Security, • Sediment Regime • Ecosystem Structure and Functioning.
  14. 14. We are trying to create a community of modellers around RS systems The community is composed by: • Model developers • Contributors • Users • Possible stakeholders The Modelling Node Community
  15. 15. Integrate Earth Observation Data (satellite, remote sensing, drones) for system analysis and data-driven modelling, allowing also for assimilation techniques to be developed Coupling of geographical domains (1D- 2D-3D interfaces) Combine similar and complementary models • Ensembles of models • Coupling of models: e.g. Hydrodynamics – morphology – vegetation – waves • Exchange of algorithms Multi resolution techniques allow us to scale up and down between global, regional and local models. Topics of interest linked with Services Computing Urban Model • Runoff • Hydrodynamics (pipes, streets, channels) • Water Quality (channels) • Real Time Control Catchment Model • Rainfall Runoff • Surface water • Groundwater • Emissions River Model • Hydrodynamics • Morphodynamics • Water Quality • Vegetation (floodplains) • Real Time Control Marine model • Hydrodynamics • Morphodynamics • Waves • Water Quality • Ecology
  16. 16. Sharing of Good Modeling Practice, software code, scripts, etc. Guidelines for modularizing scientific sub-models and modules for easy exchange between models Protocols and standards (formats) for data and file interchange – creation of a DANUBIUS specification Topics of interest linked with Services Computing
  17. 17. Topics of interest linked with Software Computing Modelling expert support Modelling Codes, manuals, updates on line, test cases Modelling Data, Visualization tools, web interfaces, basic processing Modelling Standardization and guidelines Modelling Training, courses, workshops..
  18. 18. Topics of interest linked with Software Services Cloud Computing: large model simulations (with big data) are made at external computing facilities. Large scale, detailed models using HPC centers to carry out simulations Support for parallelization to make the models make full usage of massive parallel computers Constructing models considering massive parallel usage
  19. 19. An so what? What is the added value for your research/activity? ⚫ DANUBIUS model will reach interoperability level → more tools for your activities ⚫ The DANUBIUS-RI will provide a pool of useful data to be used in your research ⚫ Standardizing approaches for RSS will give material for benchmarking and possibility to test your modeling tools ⚫ Opportunity to interact for bleeding edge modeling development (codes, algorithms) Work done by the Modelling Community through Research Projects Modelling Node Services provided through RI to researchers Core Codes and test cases Expert Support Visualization tools Standards Training Coordination to focus the modelling effort and create critical mass on River-Sea (RS) modelling topics to facilitate calls from EU on these A VIRTUOUS CIRCLE
  20. 20. Modeling Node Working Groups ⚫ WG1 Spatially integrated models in RDS systems ⚫ WG2 Interchange formats, standardization of input/output ⚫ WG3 Post processing ⚫ WG4 Water quality and pollution modeling
  21. 21. WG1: spatially integrated models in RDS systems ⚫ Coupling various sub-modules to allow the spatially integrated modelling (Drainage basin – river – delta – open ocean) ⚫ Setting up integrated model applications for river – delta – sea systems (integrated 1D-2D-3D models for supersites) ⚫ High performance computing for large scale and detailed models
  22. 22. WG2: Interchange formats, standardization of input/output Standard file format that will be used for all core models: DANUBIUS file format Easy conversion procedures to convert between native and DANUBIUS file format (The DANUBIUS file format should be applicable also to other modules that are included in the core model) A netcdf standard for unstructured files. (A similar standard exists, but is not widely used. A web group exists but DANUBIUS could take the lead on this specific aspect upgrading some system utilities of netcdf (ncview) that would work on unstructured grids. DANUBIUS-RI Modelling Node could be the common table were to work on a proposal for a standard that allows interoperability between unstructured grids Standardization will involve also groups not part of DANUBIUS-RI to maximize the benefit of this initiative.
  23. 23. Working groups 3 and 4 ⚫ WG3 Post processing ⚫ analysis processing, achieve a set of derived variables for stakeholders. To deal with techniques and methods to do postprocessing ⚫ WG4 Water quality and pollution modelling
  24. 24. Future Opportunities DISSEMINATING AND INCREASING THE COMMUNITY START PRACTICALLY TO WORK TOGETHER AND PROVE THE MODELLING NODE SERVICES - Join the discussion in the Working groups! - Discussion on a possible Pilot implementation as a demonstrator of DANUBIUS capability. We will start from the modeling node but the idea is, at the end, to be able to provide an example of an integrated approach, involving also the other nodes (starting from the observation node).
